Abdominal jugular venous return test

The abdominal jugular vein reflow test is an auxiliary test for checking the normality of venous blood vessels. With the jugular vein reflux test. The principle is that the abdominal pressure is increased by pressing the abdomen, and the liver is indirectly pressed by conduction, and the blood volume is increased. Through this examination, the corresponding symptoms can be judged. The patient is lying on his back and breathing calmly. The examiner's right palm is pressurized on the patient's umbilical circumference, and the pressure is from small to large. The jugular vein filling is observed while pressing. Basic Information Specialist Category: Cardiovascular Examination Category: Other Examinations Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: Normally, the compression of the liver by hand does not cause the jugular vein to swell, and the hepatic-jugular venous return sign is negative. Positive: This sign is an important sign of right heart failure, cardiac tamponade, constrictive pericarditis, restrictive cardiomyopathy, and tricuspid stenosis. When the abdomen is pressed, the blood flow to the inferior vena cava and the right ventricle is increased. Due to right heart failure or right ventricular diastolic restriction, the right atrial pressure is increased due to blood stasis, and the right atrium cannot fully receive the refluxed blood. Causes an increase in jugular vein filling. Tips: Maintain a normal diet and routine before checking. Normal value Normally, the compression of the liver by hand does not cause the jugular vein to swell, and the hepatic-jugular venous return sign is negative. Clinical significance Abnormal result This sign is an important sign of right heart failure, cardiac tamponade, constrictive pericarditis, restrictive cardiomyopathy, and tricuspid stenosis. When the abdomen is pressed, the blood flow to the inferior vena cava and the right ventricle is increased. Due to right heart failure or right ventricular diastolic restriction, the right atrial pressure is increased due to blood stasis, and the right atrium cannot fully receive the refluxed blood. Causes an increase in jugular vein filling. People who need to be examined: patients with cardiovascular disease. Positive results may be diseases: tricuspid stenosis, constrictive pericarditis, restrictive cardiomyopathy, myocarditis considerations Taboo before the test: maintain a normal diet and rest. During the examination, the patient should be supine, open his mouth and breathe smoothly, and use his right hand to press the patient's right upper abdomen for 30 to 60 seconds. If the jugular vein shows significant expansion, or the jugular vein beats more than 1 cm, it is positive for the jugular vein return. Inspection process The patient is lying on his back and breathing calmly. The examiner's right palm is pressurized on the patient's umbilical circumference, and the pressure is from small to large. The jugular vein filling is observed while pressing. Not suitable for the crowd Inappropriate people: Generally, there is no suitable for the crowd. Adverse reactions and risks Nothing.
